(1918) ‘The Great War’ nears its end as German defense is smashedFourteen Allied divisions assault the Hindenburg Line, a series of heavily defended positions protecting a German army in semi-retreat. With help from a new weapon, the armored tank, the 30th Infantry breaks through at the Battle of St. Quentin Canal, dealing a decisive blow to the Germans.The Battle of St Quentin Canal was a pivotal battle of World War I that began on 29 September 1918 and involved British, Australian and American forces operating as part of British Fourth Army under the overall command of General Sir Henry Rawlinson, 1st Baron Rawlinson. Further north part of the British Third Army also supported the attack, whilst to the south of the twelve-mile Fourth Army front the First French Army launched a coordinated attack on a six-mile front. The objective was to break through one of the most heavily defended stretches of the German Siegfriedstellung, which in this sector utilised the St Quentin Canal as part of its defences. The assault achieved its objectives, resulting in the first full breach of the Hindenburg Line, in the face of heavy German resistance. In concert with other attacks of the Great Offensive along the length of the line, Allied success convinced the German high command that there was little hope of an ultimate German victory.
